# Email
|
|
|
|
All email is stored on a GCP instance, which runs Postfix and Dovecot.
|
|
|
|
This host receives all email for both `chriscowley.me.uk` and `cowley.tech`, but does not forward/send them.
|
|
|
|
!!! note "Why not send through this host?"
|
|
|
|
First, GCP block outgoing SMTP connections on several ports. Second, email forwarding is based on reputation and I can't be bothered to deal with it.
|
|
|
|
For a long time I used [Mailjet](https://app.mailjet.com) for sending emails, but then switch to [SMTP2Go](https://smtp2go.com) because it allows more key/secret pairs. These need to be configured on the clients (Thunderbird, Evolution, phone, whatever).

## TLS Certificates
|
|
|
|
Managed using LetsEncrypt using a really simple script:
|
|
|
|
```bash
|
|
/root/renew_certs.sh
|
|
```
|
|
|
|
It runs daily to renew all certs on that host
|
|
|
|
|
|
## Backup
|
|
|
|
Backups use [Restic](https://restic.readthedocs.io/en/stable/) and are stored in Backblaze B2. The bucket is called `instance2-backup`.
|
|
|
|
There are 2 scripts for the backups:
|
|
|
|
```bash
|
|
/usr/local/bin/clean-backup
|
|
/usr/local/bin/run-backup
|
|
```
|
|
|
|
The backup is run every day and the clean up runs once a week.
